Connecting new toilet to unused drain

[burg]

Hi all, as part of a slow DIY bathroom refit I've removed the old toilet from the original location next to the soil pipe and plan to place it the opposite side of the room. I was pretty lucky to find a 110mm sewer waste pipe below the old sink which is the location of the new toilet so need to connect the toilet up to this now.

 

There's no existing above ground pipework there as you can see in the attached images. The toilet is a back to wall version so the pan connector needs to go straight out from the back of the toilet, 90 degree bend left and then down into the drain waste. I'm aware of 3 drain points on our ground floor with the main stack that services the upstairs bathroom vented through the roof, as far as I can tell that means I don't need to vent this toilet as it's the only connection on this new stack but I could add an AAV if required. 

 

The plumber said there's no issue in doing it when he was out months back and to call him when I want it done but I thought I'd see how easy a DIY job it is first, given I've done most of the bathroom so far. I'd also rather avoid flexi waste pipes if possible.

 

From my understanding I'll maybe need this pipework : 

 

• MCALPINE PUSH-FIT SINGLE SOCKET DRAIN CONNECTOR BLACK 110MM
• FLOPLAST PUSH-FIT 92.5° DOUBLE SOCKET BRANCH BLACK 110MM - Out from the drain connector, don't need the side bosses, will cap the top unless it requires an AAV - good to have the option to easily add one though I guess.
• MCALPINE RIGID STRAIGHT WC CONNECTOR - The toilet pan connector is embedded in the back to wall toilet so will need to extend out to the pipework.
• Unsure - some form of swept 90 degree bends to connect all of this up, perhaps some straight 110mm soil pipe too, it's a very short run.

 

I'm willing to have a go this weekend before calling a plumber given screwfix is just around the corner and has a pretty good returns policy so any guidance first would be appreciated!

I did add images but I'm not able to see them on the post...?
